cg-k.com

We performed a comprehensive analysis of cg-k.com on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 18391ms. The page is served over HTTP/1.1 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 406 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Let's Encrypt (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 3 domain(s) (Subject Alternative Names) and expires on 2026-07-29, which is 31 days from now. The security headers analysis reveals a score of 15/100 (poor). The following security headers are properly configured: Permissions-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 11 technologies across 9 categories powering cg-k.com. The detected stack includes WordPress, Next.js, Google Analytics 4, Microsoft Clarity, Google Ads, Google AdSense, Cloudflare, Google Fonts, YouTube Embed, jQuery, and Font Awesome. The site uses Next.js as its primary framework. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, cg-k.com receives an overall trust score of 60/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, cg-k.com receives a trust score of 60/100, which places it in the "Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, a valid SSL certificate issued by Let's Encrypt with 31 days until expiration, and a well-established domain registered for over 8.2 years, indicating long-term commitment and legitimacy. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked cg-k.com against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers. The domain is registered through GMO Internet Group, Inc. d/b/a Onamae.com based in JP, with a registration date of 2018-04-06 and expiration date of 2027-04-06.

cg-k.com delivers its homepage in 18391ms (server response time), which is considered slow by industry standards. The total page weight is 406 KB, and we detected 421 resource requests loading assets from 57 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 4 out of 16 CSS files and 15 out of 20 JavaScript files are minified. Minifying the remaining 17 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of cg-k.com produces approximately 0.2g of CO₂, earning a carbon rating of B. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 406 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for cg-k.com. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

cg-k.com resolves to the IPv4 address 163.44.185.168, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: dns01.muumuu-domain.com and dns02.muumuu-domain.com. Having 2 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for cg-k.com is handled by lolipop.jp with 1 MX records configured: mx01.lolipop.jp. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. DMARC is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for cg-k.com. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions. The domain is registered through GMO Internet Group, Inc. d/b/a Onamae.com (JP). It was first registered on 2018-04-06 and is set to expire on 2027-04-06, making it 8.2 years old. Our subdomain enumeration scan discovered 1 active subdomains for cg-k.com: www.cg-k.com. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of cg-k.com contains 1,003 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing. The page is structured with 11 H2 headings, 19 H3 headings, 13 H4 headings. The page includes 121 images. 101 images (83%) are missing alt text attributes, which is a significant concern for both accessibility and SEO.
